* Set receive enable and transmit enable bits of SCASCR0 (E6C400089).
  Values previously written to this register was bogus.

  Curiously earlyprintk works with the previous code.

* Remove duplicate initialisation of GPIO port 152, SCIFA0_TXD (0xE6053098).
  This should have no effect other than to very slightly reduce the amount of
  code.
